Chapter 1124 It Will Be Solved
Tang Changhong and Liu Daxiang, who had discussed it, took a special time to chat with Zhang Qihang at the dinner in the evening and asked him what he meant.

After listening to Tang Changhong and Liu Daxiang, Zhang Qihang was silent for a while, and then said seriously: "Academician Liu and Tang Gong, your proposal is very good and very constructive, and our group is also very constructive, but I have a few concerns...or questions."

Hearing Zhang Qihang's words, Tang Changhong and Liu Daxiang smiled at each other, and they both nodded at the same time: "Mr. Zhang, if you have any questions, just ask."

Zhang Qihang had something to say, which was expected by the two of them.

"You two also said just now that this is a high bypass ratio turbofan engine developed based on the core engine of the 'Taihang A' fighter jet with a small bypass ratio turbofan engine. If our Huateng Group wants to take over this project , it is necessary to have a comprehensive understanding of all the core parameters of the 'Taihang A' project..." Speaking of this, Zhang Qihang said seriously: "Don't you and the leaders above worry about leaks?"

As soon as Zhang Qihang's voice fell, Liu Daxiang smiled: "I knew Xiao Zhang that you would say that...well, I won't say too much, there are only three of us here, so I will say something from the bottom of my heart: If the country is worried that these former Soviet experts from your group or your group are unreliable, do you think your group’s D-30KP-3 engine can be installed on the H6?”

"That's the truth," Zhang Qihang immediately laughed when he heard what Liu Daxiang said, and nodded again and again: "Since the country can allow the D-30KP-3 engine designed by our group to be installed on the H6 aircraft, it will naturally believe us... "

Liu Daxiang and Tang Changhong were overjoyed immediately, and they both felt that Zhang Qihang had already said this, so the matter was probably settled.

But what Zhang Qihang said next made the two of them stunned...

"However, there are some problems, that is, what about the research and development funds? Is it the state's input or our Huateng Group's own money? Or is it part of the state's contribution and our group's own part?" Zhang Qihang said: "If it is such a model, who owns this turbofan engine with a large bypass ratio after it is produced? How should ownership and mutual responsibilities be divided?"

"This one……"

Hearing Zhang Qihang's words, Academician Liu and Tang Gong were stunned.

The two of them thought things were too simple before and didn't consider this factor at all, but now they heard what Zhang Qihang said, and they also instantly realized the problem and trouble.

Zhang Qihang went on to say: "If it is said that it is all owned by us, after all, the country has invested so much money and resources in it before, we feel flustered if we hold it by ourselves; but if it is still completely owned by the country, this... Mr. Tang , Academician Liu, let's tell the truth, in the current state, this project is actually not much easier than starting from scratch, so..."

"Understood," said Zhang Qihang, Academician Liu and Tang Gong already knew that today's conversation cannot be carried out. If these things are not sorted out, this matter cannot be discussed at all.Academician Liu immediately said: "Mr. Zhang, the problems you mentioned are indeed very practical problems, but in my opinion, these are not problems. As long as everyone is for the development of national defense, then these problems and Analysis can actually solve it, don’t you think?”

Now that we have talked about this, how can Zhang Qihang still say no?He smiled and nodded: "You are right, these problems do exist, but they can all be solved."

Academician Liu agreed with Zhang Qihang's words: "Yes, as long as everyone is running towards the same goal, no matter what problem there is, it can be solved."

Academician Liu is also a decisive person. After realizing that he had thought things too simply, he immediately stopped today's conversation on the point of "reaching a consensus": as long as the two sides can reach the most basic consensus, Then the rest of the questions are fine.

Beijing.

In Mr. Zhang Heen's home, Mr. Zhang, who is rarely at home in leisure time, smiled at Liu Daxiang who was sitting on the sofa next to him, and joked: "I said, old Liu, you old guy came here because of the smell, right? I just took a rest In a few days, you chased and killed him?"

Yes, from the official establishment of the project in 1987 to last month, Mr. Zhang Heen's leading "Taihang" project was formally finalized. The old man had a relatively free time, and it was hard for him to relax at home. This guy Liu Daxiang He even chased him to the door...

Of course, "chasing and killing" is what Mr. Zhang jokingly said to his old friends. In fact, Mr. Zhang Heen was too happy that Liu Daxiang could take the initiative to visit him.

Academician Liu Daxiang chuckled, shook his head lightly, and said to Mr. Zhang Heen: "What do you mean by chasing after you? I'm here to brag to you. Let me tell you, this time I went to Lu Province, and I really gained my knowledge. .”

"Oh?" Hearing what an old friend said, Mr. Zhang Heen was really curious: "That D-30KP-4 of Huateng Group has a very powerful performance?"

华腾工业集团的那些前苏联的航空发动机专家，在D-30KP-3发动机的基础上有推出了一个D-30KP-4方案，据说推力最大能到145到150千牛，听说自己的老朋友就是为了这个方案去的鲁省。

After hearing about this incident, how could Mr. Zhang Heen not be curious about this plan?If he hadn't been too busy with work some time ago, he would have followed along to join in the fun.

"It's not just powerful, it's simply domineering!"

Academician Liu Daxiang nodded vigorously, and said: "The D-30K engine has actually changed them to a bypass ratio of 4.2 and a maximum thrust of 145 kN. Do you think this is an exaggeration?"

Zhang Heen's eyes widened: "You mean, their plan is feasible?"

"Why is it not feasible?" Facing the suspicion in his old friend's words, Academician Liu smiled: "Don't forget, they have come up with D-30KP-3 before, and Lao Zhou of Xifei is very concerned about the performance of this engine. Very satisfied..."

The implication is that although the D-30KP-3 of Huateng Industrial Group has not completed the whole process of airworthiness certification, the process of airworthiness certification of the entire engine has been very smooth in the past few years, and I have never heard of any bad news. It is rumored that this plan and design are very mature. It is not uncommon for you, Zhang, to know about the engine testing process. What is there to doubt?

"..."

Hearing what his old friend said, Zhang Heen realized for a while that his words were not very appropriate: Yes, D-30KP-3 is a design highly recognized by Xifei's Lao Zhou. After seeing Huateng Group's D-30KP-3 Afterwards, that guy from Lao Zhou immediately "loved the new and disliked the old" and left the D-30KP-2 that he had been thinking about before... Having said that, since the Huateng Group can come up with the D-30KP-3, then the D-30KP-3 On the basis of -30, take out a D-4KP-[-], what can't be understood?

What I said just now is indeed a bit inappropriate.

Thinking of this, Zhang Heen said with a smile: "Fortunately, I didn't say this in front of Xiao Zhang, otherwise I would lose my face...Old Liu, tell me, compared to D-30KP- 3. What improvements and optimizations have been made to this D-30KP-4?"

As soon as he mentioned this, Liu Daxiang immediately became energetic: "They really have a lot to improve and optimize, let me tell you..."

Listening to Liu Daxiang's narration, Zhang Heen pondered from time to time, or nodded suddenly...

After hearing Liu Daxiang finished speaking, Zhang Heen said with emotion on his face: "The old guys from the former Soviet Union in the Huateng Group are really powerful, and they have played tricks on the aero engine - to tell you the truth Said, when the 'Taihang' was finalized before, I was somewhat complacent in my heart, but now hearing what you said, compared with the former Soviet experts of the Huateng Group, we seem to be nothing special..."

Academician Liu Daxiang was taken aback by Zhang Heen's emotion. He thought his words had stimulated his old friend, so he said quickly: "It's impossible to say that. People like Antonov and Yaroslavsky belonged to the aviation industry of the former Soviet Union. The top talents you have cultivated, and Lao Zhang, your achievements are not weaker than theirs..."

"What are you talking about?" Zhang Heen couldn't laugh or cry when he heard the words: "I just felt that I was a little complacent before, and I sighed, and it can be regarded as urging and urging myself. Where are you going, old Liu... It's you, Old Liu, I'm a little curious, you are a busy person, why are you suddenly free to brag with me today?"

Hearing what Zhang Heen said, Liu Daxiang stopped going around in circles with him, nodded and said, "I'm here to look for you, I really have something to do."

For Liu Daxiang's answer, Zhang Heen was not surprised at all, he nodded: "What's the matter, tell me."

In fact, when Liu Daxiang contacted him by phone earlier, Zhang Heen guessed that this guy must have something to do with him.

The old friends talked about this, and Liu Daxiang naturally stopped going around in circles: "That's the thing, you told me about an idea before, saying that the quality and foundation of the core machine of 'Taihang' are very good. Based on the core engine of the 'Taihang' engine, it is relatively easy to develop a high bypass ratio turbofan engine suitable for large jet transport aircraft with a bypass ratio above 5, right?"

Zhang Heen nodded immediately: "Yes, there is such a thing."

"Then from the perspective of your 'Taihang' chief engineer, what do you think the maximum thrust can be if such a large turbofan is built on the basis of the 'Taihang' core machine?"

Although Liu Daxiang's question was a bit strange to some extent, Zhang Heen still answered seriously: "For the maximum thrust, it is not a big problem to reach 140 kN."

Speaking of this, Zhang Heen half-jokingly said to Liu Daxiang: "What? Old Liu, do you want to do this project? If you want to do this project, I have no problem, and I will definitely support you."

"I'll forget it," Liu Daxiang smiled and waved his hands, then changed his tone, and said to Zhang Heen: "But I want Huateng Group to do this project, what do you think?"

"..."

Mr. Zhang Heen was stunned for a while, then looked at Liu Daxiang in surprise, and said, "Old Liu, what are you kidding? You just said that the maximum thrust of the Huateng Group's D-30KP-4 engine solution can be easily achieved. When it reaches 150 kN, people leave their own projects behind and hang around behind our team?"

"I'll tell you the truth," Liu Daxiang sighed, and said, "Comrade Zhang Qihang admitted it himself, although they are indeed sure that the maximum thrust of the D-30KP-4 will reach 145 to 150 kN, but the problem is This engine is based on Lao Maozi’s D-70K technology in the 30s, and its thrust of 150 kN is already the limit of the potential of this engine, and the fuel consumption and noise control may not be very ideal.”

"Well, almost." Zhang Heen thought for a while, nodded and agreed with Liu Daxiang's words: "Although I haven't carefully understood the D-30KP-4 plan of Huateng Group, I think Comrade Zhang Qihang's words are very reasonable. After all, D The foundation of -30K is here, and the potential is almost reaching the limit."

"Really? You think so too?" Liu Daxiang nodded and said, "Didn't your team mention the idea of ​​building a turbofan with a large bypass ratio on the basis of 'Taihang' before? But the problem is that your team Next, we have to work on 'Taihang A', maybe there will be 'Taihang B' and 'Taihang C' in the future...I'm afraid I don't have time to do this project.

So I thought, since you don't have time to do it, and the potential of the D-30KP-4 from Huateng Group has reached its limit, can you two cooperate with each other, so that you can concentrate on the "Taihang" series, and Should the high bypass ratio turbofan project based on the 'Taihang' core machine be handed over to Huateng Group? "

"..."

This time, Zhang Heen didn't speak immediately, but after frowning and thinking for a while, he asked Liu Daxiang: "Is this suggestion made by Comrade Zhang Qihang?"

In Zhang Heen's view, there are nine out of ten reasons that Huateng Group is eyeing its own "Taihang."

But Liu Daxiang's answer was beyond Zhang Heen's expectation. He shook his head and said, "No, I proposed it."

Academician Liu Daxiang then added: "Comrade Zhang Qihang and I mentioned this idea..."

"What did Comrade Zhang Qihang say?"

"Comrade Zhang Qihang's opinion is that if it is from a purely technical point of view, there are not many problems here, but there are many difficulties in actual implementation, such as the division of full responsibilities, research and development funds, etc..."

Hearing what Liu Daxiang said were all irrelevant things, Zhang Heen couldn't help it: "Aren't you worried about leaking secrets?"

"Secret leak?" Liu Daxiang smiled: "If we are worried about leaking secrets, what about D-30KP-3? Besides, we still import AL-31F in large quantities from Lao Maozi every year, so don't worry about it." Leaked secrets? We don’t even worry about these things, but instead worry about where Zhang Qihang will leak the secrets?”

"Uh……"

Mr. Zhang Heen was speechless: It seems that this is the truth.
